I've measured hundreds of shirts over the years, and nothing throws off a merch drop like inconsistent sizing. When I first worked with AstralSpiff on his 2024 collection, we spent weeks dialing in garment specs to match his fans' preferences. Now in 2026, his store offers hoodies, tees, tank tops, and hats that fit reliably if you know what to look for. This AstralSpiff sizing guide will walk you through every item type so you can order with confidence.
Hoodie and Crewneck Sizing
Hoodies and crewnecks are the cornerstone of AstralSpiff's merch line. They're made from a 280gsm cotton-polyester blend that resists shrinkage, but the cut is meant to be relaxed. Most fans like a slightly oversized look for comfort.
Size Chart for Hoodies
| Size | Chest (in) | Length (in) | Sleeve (in) |
|---|---|---|---|
| S | 36-38 | 27 | 33 |
| M | 39-41 | 28 | 34 |
| L | 42-44 | 29 | 35 |
| XL | 45-48 | 30 | 36 |
| 2XL | 49-52 | 31 | 37 |
| 3XL | 53-56 | 32 | 38 |
Measurements are garment dimensions, not body measurements. If you normally wear a Large in other brands, stick with Large here for a classic fit. For a baggier feel, go one size up.
Common mistake: Assuming a 280gsm hoodie will shrink significantly. It won't. Pre-shrunk fabric means what you get is what you keep.
T-Shirt and Tank Top Fit
Tees and tanks use a 180gsm 100% ring-spun cotton. The fit is standard - not skinny, not boxy. They work well for most body types without being too clingy or too loose.
T-Shirt Size Chart
| Size | Chest (in) | Length (in) |
|---|---|---|
| S | 35-37 | 27 |
| M | 38-40 | 28 |
| L | 41-43 | 29 |
| XL | 44-46 | 30 |
| 2XL | 47-49 | 31 |
| 3XL | 50-53 | 32 |
Tank tops follow a similar chest range but are 2 inches shorter in length. If you're between sizes, choose the larger size for a relaxed look or the smaller for a closer fit.
Pro tip: If you plan to layer a tee under an AstralSpiff hoodie, order the same size in both. The tee's chest measurement is 2-3 inches smaller than the hoodie's, so they stack well without bunching.
Hat and Accessories Measurements
Hats come in two styles: snapback (adjustable with plastic snap) and dad hat style (adjustable with metal buckle). Both are one-size-fits-most but require a head circumference between 21.5 and 24 inches.
How to Measure Your Head
Wrap a soft tape measure around your head approximately 1 inch above your eyebrows and ears. If you don't have a tape, use a string and then measure it against a ruler.- Under 21.5": These hats may feel loose even on the tightest setting.
- 21.5" - 24": Perfect fit range. The snapback has 7 adjustment positions; dad hat has an adjustable strap.
- Over 24": The hat might not fit securely. Consider custom options or look for extended sizes elsewhere.
Other accessories like beanies and socks are stretchy and fit most adults. One size fits all, typically head circumference 21-24 inches for beanies and US shoe sizes 6-13 for socks.
How to Measure Yourself
Getting accurate body measurements is key to using any size chart. Here's a quick method:
Step 1: Chest
Stand naturally with arms at your sides. Wrap the tape under your armpits and around the fullest part of your chest. Keep the tape level and snug but not tight.Step 2: Waist
Find your natural waist - the narrowest point above your belly button. Wrap the tape around without pulling it tight. For hoodies and tees, this measurement matters less than chest, but it helps for tanks and fitted styles.Step 3: Hips (if needed for longer tees)
Measure the widest part of your hips, about 8 inches below your waist. This helps ensure longer shirts don't ride up.Step 4: Sleeve Length (for hoodies)
Bend your arm slightly. Measure from the center back of your neck, across your shoulder, down to your wrist bone. This is easier with a friend's help.Common mistake: Measuring over bulky clothes. Always measure in thin layers or directly on skin for accuracy.
Common Mistakes to Avoid
- Mixing up garment and body measurements: The numbers on the size chart are the actual dimensions of the shirt lying flat. Your body chest should be about 2-4 inches smaller than the garment chest for a comfortable fit.
- Ignoring fabric weight: A 280gsm hoodie drapes differently than a 180gsm tee. Heavier fabrics pull down slightly, making length seem longer. Check the product page for fabric specs.
- Blindly trusting your usual size: AstralSpiff's fit is consistent, but every brand's size charts vary. Always compare your measurements to the chart for that specific item.
- Not accounting for layering: If you plan to wear a hoodie over a hoodie (some fans do this for extra warmth), go up 2 sizes. For a tee under a hoodie, same size works.
Pro Tips from the Community
AstralSpiff's Discord community has years of ordering experience. Here's what they've shared:
- The 2-inch rule: For a relaxed fit that still looks intentional, add 2 inches to your chest measurement and find the size with that garment chest. For example, if your chest is 40 inches, look for a garment chest of 42 inches (size L in tees).
- Order a size up for hoodies if you're between M and L: The sleeves on hoodies are generous, but length stays proportional. Going up avoids pulling at the shoulders.
- Wash cold, hang dry: The 180gsm tee is pre-shrunk, but hot drying can still cause up to 3% shrinkage. Hang drying preserves the fit for years.
- Check the product images for fit reference: AstralSpiff sometimes includes pics on different body types. Compare those to your build.
